Purity & Potency

All of our raw materials are tested for identity, potency, microbial contaminants, heavy metals, solvent residue and allergens. Herbal ingredients are also tested for different pesticide compounds and essential fatty acids and fish/krill oils are tested for oxidation markers and environmental contaminants, including PCBs and dioxins.

Our comprehensive allergen procedures allow us to confidently prevent ingredient cross-contamination. Formulas undergo stability studies to ensure potency throughout shelf life.
